Usage notes

ICAO code KOAK. Amelia Earhart began her final round-the-world attempt from Oakland in 1937. In 2024 the Port of Oakland renamed the airport "San Francisco Bay Oakland International Airport," prompting a trademark lawsuit from the City of San Francisco, which owns SFO. The OAK code itself was never in question.
